Proof step 37 from proof isobj-addobj-04 (previous step)

fis .keys = instfields(class), validfieldinits(fis, st) ⊦ r = jvmref, r ≠ jvmref ∧ r -- _type ∈ addobj(r, class, fis, st) ∧ is_typevalue(addobj(r, class, fis, st)[r -- _type]) ∧ is_classtype((addobj(r, class, fis, st)[r -- _type]) .type) ∧ is_obj(r, (addobj(r, class, fis, st)[r -- _type]) .type .class, addobj(r, class, fis, st))

And obtained the following new goals

Proof step 2:
⊦ r -- _type ∈ addobj(r, class1, fis, st)
Proof step 3:
⊦ fis .keys = instfields(class) → ¬ _type ∈ fis
Proof step 4:
¬ _type ∈ fis ⊦ (addobj(r, class1, fis, st)[r -- _type]) = typeval(mkclasstype(class1))
Proof step 36:
fis .keys = instfields(class), validfieldinits(fis, st) ⊦ r = jvmref, is_obj(r, class, addobj(r, class, fis, st))
